GOVERNOR.

vSpeciificaton of Letters Patent.

To `all 'whom 25 may concern;

Be it known that I, RQBERT PYLE, of Indianapolis, 'county of Marion,and' State of Indiana, .have invented a certain useful Governor; and Ido hereby declare that the ,Y following is a full, clear, and exactdescrip` :tion thereof, reference being had to the accompanyingdrawings.

tion of the rI he object Iof,- this invention is to provide. animprovedconstruction of centrifugal governor particularly adapted lforcontrolling valves or other. lmechanisms' for steam engines:4

The nature of 'the invention will be. understoodl from the accompanyingdrawings and the following description and claims, In the drawings,Figure 1 is a side elevatical v:l()1 1g;itudinal section through thesame. Fig. 3 1s a plan view. Fig. 4 is a section similarto Fig; 2showing the parts actuated.

. 15 and between them balls are located formj Fig. 5 is a section on theline 5-5 of Fig. 2.

In the drawings there shown a ,shaft 10 mounted in a iXed frame 11.. .Acasing 13 surrounds the shaft 10 and has a reduced portion 14 which.hugs the shaft `10 but is slidable longitudinally ythereon.' A' bearing15 'surrounds the reduced portion 14 in said casing. A bearinglsurroundsthe bearing ing a ball bearing. A band 17 surrounds /saidbearing and on its opposite sides there are pins 18 which engagethevlower ends of a yoked bar 19. The yokeis astride the (band 17 andat-eac'h side at120 the'yoke is .fulcrumed to abar 21 from theiXed frame11. A rod 22 is pivoted to the-upperend of the 'bar 19 and from it powerisv transmitted to the device which is to be governed, asv the sleeve 14slides to and fro on the shaft 10.

The 'casing ,13 not-V only has` the reduced portion 14 at oneend, buthas an enlarged the left-hand said ribs 27 there is .a longitudinalslot:` 28` 'mik left, as shown 1n Fig.` 3, and each projecting' portionvhas a air of longitudinal Y ribs 27, as shown, and

etween the left-hand ends of which extends from the left-hand end almosthalf thev length of the casing: ring 30 lmovement, after the same havegovernor in idle condition, parts. being broken away. Fig. 2 is acentral ver.

forms the left-.hand end of'the casing, being integral with the taperedends thereof and t-he ribs 27. The ring 30 is contracted, asl

shown in Fig. 4, .so as to loosely engage a fixed` sleeve 31surroundingV the shaft 10. Said sleeve 31 is pinned to the shaft bye,Ypin 32. The major portion of the sleeve 31 projects into the enlargedport-ion of the casing,

see Fig. 2, ,and at itsinner end is externally threaded for the ringnuts or collars 33. A

`helical spring 34 surrounds the sleeve 31 and runs between the collars33 at one end and the inwardly turned end 131 of-the casing- 31 so thatsaid spring tends to return the casing and parts giving them a left-handbeen operated.`

their ends at 41 to extensions 42 from the left-hand endV of the sleeve31, `being that vportion which lies outside of the casing 13. The bodywith the shaft and to the right and operates through the openings 28 inthe casing 13. A

Asvthe rotative speed of the shaft 10 increases centrifugal force willthrow the 'weighted ends of the arms 40 outwardly, as

shown in Fig. 4,. and the otherends of said levers by bearing againstthe left-hand end of thecasing 13, that'is the ring portion 30,

of the weights extends parallel' Weighted levers 40 are 'fulcrumedbetween will-sl-idesaid casing 1.3 to the right and thereby actuatethe-lever l9 and the means which is to be governed. y .I claim -as myinvention: 1. The combination with a shaft, of a centrifugal governorconsisting of a casing surfA rounding `the same and having at one end areduced portion slidable on the shaft and at the other endan enlargedport-ion, means adapted to be actuated by the slidingmove.

ment of said casing for controllingl the thing to be governed, a sleevesecured to and surrounding the shaft and projecting into the enlargedportion' of thel casing, a pair of weighted levers pivoted to oppositesides of said fixed sleeve and adapted when actuated by centrifugalforce to slidably move said casing on the shaft, and Ea spring bet-Weensaid sleeve and casing tending to return the latter.

2. The combination with a shaft, of a centrifugal governor consisting ofa casing surrounding the same and having at one end a reducedortionslidable on the shaft and at the vnt erend an enlarged portionwith the casing and externally threaded on its inner end, a collar onthe threaded end of said sleeve, a helical spring Within the enlargedportion of the casing and surrounding said sleeve and lying between saidcollarand the contracted end-fof the sleeve, arms extending from theportion of the sleeve outside the casing, and weighted-levers fulcrumedto the ends of said arms With the ends engaging the contracted end ofthe casing so as to move the same under the iniuence of centrifugalforce against said spring.

3. The combination with a shaft, of a centrifugal governor consisting ofa casing surrounding the same and having at one end a reduced portionslidable on the shaft and at the other end an enlargedl portion with acontracted end and out partially away on opposite sides and the portionswhich are not cut away being reinforced by parallel longitudinal ribsand with an opening through the easing between said ribs, means adaptedto be actuated by the reduced p0rtion of said easing for controlling'thething to be governed, a sleeve secured to and surrounding the shaft andprojecting into the enlarged portion of the casing and externallythreaded o-n its inner end, a collar on the threaded-end of said sleeve,a helical spring Within the enlarged portion of the casing andsurrounding said sleeve and lying between said collar and the contractedend of the sleeve, arms extending from the portion of the sleeve outsidethe casing,' and weighted levers fulcrumed on the ends of said arms withthe Weighted portion oper ating through the ,openings in theside of saidcasing and with the other ends of the levers 'engaging the reduced endsof said casing for slidably moving the same against the action of thespring when 'the levers arey influenced by centrifugal force.

In witness whereof, I have hereunto affixed mysignature in the presenceof the wit-nesseshereinnamed.
